However IMHO.. I don't believe a 67-68 fastback style, would look right on the current Stang, unless the car's beltline is lowered.. as it currently sits too high as is.
Otherwise, both the rear glass and trunk sections..will appear to look way too high/flat..
Perhaps these are some of Ford's reasons, for not designing the current Mustang as a full fastback..
Here is a '06 beside a '66. It is clear to see how much taller the S197 is and how adding more to the back half would make it even bulkier.
What's the difference ? as the waistline on the 65-66..is the same height as the 67-69's anyhow...A '66 is not really a good example because, personally, I don't like them nearly as much as the 67-69s.
Compare an S197 with a '67 or '69 fastback
I couldn't agree more, as Ford took design elements from (65-66) Shelby quarter windows (67-68) dash/gauges/hood/grille/headlights/fogs, and (69-70) tail lights..
Thus, the S-197 is indeed.. a metamorphosis between modern and classic design, in which gives the car it's own unique identity...While at the same time, remaining true to it's heritage..
As one thing is for certain ! at least nobody can accuse Ford, of attempting to duplicate it's success, from any of their classic designs lol.
